32bit libstdc++.so not found on 64bit CentOS 6.3 system

The GNU Standard c++ library libstdc++.so.5 is a core library for CentOS system. Most of the operating systems comes with a version of libstdc++ in sync with architecture ( i.e., 32 bit or 64 bit system ) of OS. That is 64 bit OS have 64 bit libstdc++.

However to install various other tools and compiler like intel compiler, on a 64 bit system, we require to have 32 bit compatible version of libstdc++ as well. Otherwise the installation will fail.
To get around this problem, download compat-libstdc++ for your os and install. This will install 32 bit compatible version of libstdc++ on 64 bit system.
